In northeastern Hangzhou's outskirts area nestles a block which is titled as 24th Street. With the boom in real estate industry, the block has brought together a number of migrant workers since 2010.

Pan Zhiqi, a teacher of Communication University of Zhejiang, spent seven years following Lao Su, a migrant worker, and his girlfriend, and turned their story into a documentary called 24th Street.

During the recently concluded 2nd West Lake International Documentary Festival, an annual event to honor excellent documentaries, 24th Street took home the Best Feature-Length Documentary award.

The festival, which ran from Oct 18 to 20, was jointly held by Administration of Press, Publication, Radio, Film and Television of Zhejiang province and the Hangzhou-based China Academy of Art.
